BACKLOG FOR FIREPLACES Filed June 12, 1968 United States Patent3,502,067 BACKLOG FOR FIREPLACES Raymond Hickman, P.0. Box 141, Pulaski,Tenn. 38478 Filed June 12, 1968, Ser. No. 736,304 Int. Cl. F24b 13/02US. Cl. 126120 4 Claims ABSTRACT OF THE DISCLOSURE This inventionrelates to fireplace devices, and more particularly to a backlog forfireplaces.

It is therefore the main purpose of this invention to provide a backlogfor fireplaces which will consist of a plurality of large diameter pipeswhich are welded to a pair of spaced apart small diameter pipes.

Another object of this invention is to provide a backlog for fireplaceswhich will have the small diameter pipes welded to the bores of thelarge diameter pipes eccentrically which will enable the device to layagainst the back of the fireplace and will prevent the device fromrolling forward when the fire goes out.

A further object of this invention is to provide a backlog forfireplaces which will be of such construction as to keep from turningover when the fireplace is full of wood, and the spacing between thepipe elements of the device is such that there will be sufiicient roomfor a draft when the wood is placed against the backlog device.

Other objects of the present invention are to provide a backlog forfireplaces which is simple in design, inexpensive to manufacture, ruggedin construction, easy to use and efficient in operation.

These and other objects will be readily apparent upon a study of thefollowing specification together with the accompanying drawing wherein:

FIGURE 1 is a front elevational view of the present invention shownpartly broken away; and

FIGURE 2 is a section taken along the lines 2-2 of FIGURE 1.

According to this invention, a backlog for fireplaces is provided with apair of large diameter or outer pipes 11 on each end of backlog 10 whichare spaced apart from the center by an outer pipe 11' of similardiameter. A pair of spaced apart small diameter inner pipes 12 aresecured within the ends 13 of pipes 11 and 11. Pipes 12 are weldedeccentrically to the bores 14 of pipes 11 3,502,067 Patented Mar. 24,1970 and 11'. A pair of T-shaped configurated bars 15 are welded to thebottoms of the outer periphery of pipes 11 and provide support means forbacklog 10 upon the andirons, shown in phantom (FIG. 1), within thefireplace (not shown). Each of pipes 11 and 11' is provided with anelongated slot 16 in the top thereof to allow the passage of air withinthe backlog 10.

In use, backlog 10 may be made in various sizes for various sizefireplaces. To prevent the backlog 10 from rolling forward when the firegoes out, the weight is distributed rearwardly by welding pipes 12eccentrically within the bores 14 of pipes 11 and 11. The eccentricconstruction of backlog 10 permits a better draft to the wood beingburned in the fireplace and also provides a means for the fireplace tothrow out more heat while using less wood than normally would be usedwithout the use of the instant invention.

What I now claim is:

1. A backlog device for a fireplace comprising:

(a) at least two outer pipes of large diameter having opposed open ends,

(b) at least one inner pipe having an outer diameter less than the innerdiameters of said outer pipes and adapted to be received substantiallylongitudinally within the open ends of said outer pipes, and

(c) means securing said inner pipe within said outer pipes so that theopposed ends of said outer pipes are spaced apart and the longitudinalaxis of said inner pipe is eccentric to the longitudinal axes of saidouter pipes.

2. The invention according to claim 1 in which each of said outer pipeshas an air opening through the wall of the pipe.

3. The invention according to claim 1 comprising three of said outerpipes and two of said inner pipes, said outer pipes being substantiallyaxially aligned, there being one inner pipe within and between theopposed ends of each pair of adjacent outer pipes, the eccentricity ofsaid inner pipes being such as to create a moment about the longitudinalaxes of said outer pipes in the same direction when said outer pipes aremounted in a fireplace.

4. The invention according to claim 1 further comprising bar supportmembers fixed to the bottoms of two of said outer pipes for supportingsaid backlog in a fireplace so that said backlog has a front and a rear,the longitudinal axis of said inner pipe being behind the iongitudinalaxes of said outer pipes when said backlog is supported in saidfireplace by said bar members.
